PLACING THE BLADE ON SAW
1. Raise saw frame part way.
2. Open idle and drive wheel guards.
3. Remove blade brush drive belt by loosening
thumb screw.
4.
Loosen Rite Tension® take up screw and
remove old blade. In the event of a broken blade, be
sure Rite tension® is open by turning take up screw
counter-clockwise at least six (6) times.
5.
Open each carbide guide. Reach behind each
blade guide assembly and turn the black knurled
knob counter clockwise until it stops. This pulls the
carbide block away from the blade.
6.
Uncoil new blade, WARNING: wear gloves to
protect your hands and eye protection. Make certain
blade teeth point in the direction of blade travel
which is toward the motor.
7.
Place new blade on the band wheels and fit it
into the guides. Close the carbides by turning the
black knob clockwise until it stops. It does not need
to be tight. Make sure that the blade is not riding up
on the band wheel flanges.
8.
Grasp blade on frame side and push it
toward guide bracket beam to hold it in position
while turning Rite Tension® take up screw.
9.
Tighten blade to proper tension. Blade is properly
tensioned when the take up screw is tightened until
mechanism bottoms.
10. Re-attach the blade brush belt and close
all guards.
Wheel Pitch Adjustment
If the saw blade runs too low, runs off the wheels, or
runs too high and rubs the wheel flange, a wheel
adjustment must be made.
Loosen the blade before making the following adjust-
ments.
Idler Wheel:
Blade running too low or off the wheel- adjust the
idler wheel block. Loosen the two cap screws in the
block, opposite the take up screw end, one-half turn.
Tighten the opposite two cap screws one-half turn.
Repeat if necessary.
Blade running too high and against the idler wheel
flange- The blade can become distorted, its top edge
rolled over and wheel flange will wear excessively.
To correct this, loosen the two cap screws closest to
the take up screw one-half turn. Tighten the
opposite cap screws one-half turn. Repeat if
necessary.
Drive Wheel:
Blade running too low or off the drive wheel- Loosen
the two cap screws opposite the outside end of the
wheel plate one-half turn. Tighten the two set
screws on the same end one-half turn. Repeat if
necessary.
Blade running too high, and against the drive wheel
flange- Loosen the cap screws closest to the outside
end of the wheel plate and loosen the two set
screws at the same time by the same amount.
Repeat if necessary.
Make certain all screws are tight after adjustments
have been made.
Variable Speed Drive
Model 1316S is equipped with variable speed
pulleys providing infinite speed selection between
70 and 375 feet-per-minute. See Cutting Speed
Chart for settings.
To vary blade speed, rotate handwheel clockwise to
increase speed or counter-clockwise to decrease
speed. Do not adjust the speed unless the pulley
system is in operation (spinning). The handwheel
drag is set at the factory during assembly. This drag
prevents handwheel “creep” during operation but still
permits easy adjustment. Due to normal wear and
environment, the drag setting may change. To
readjust, tighten set screw in thrust nut.
Gear Box Repair
1. Remove gear box from saw.
2. Remove four machine screws holding gear
box together.
3. Separate gear box by carefully prying castings
apart at a location near pulley shaft. Caution: Do
not use excessive force.
4. Once the gear box is open, the internal parts
may be inspected for wear.
5. Liquid plastic gasket is used to seal the gear
case, Loctite No. 51580 or equivalent.
6. Grease, Mobilgrease XHP 220 or equivalent is
recommended. The grease must have excellent
clinging characteristics. (See Lubrication).
